Application filed Apri13, 1915. Serial No, 19,010.

To allwhom it may concern Be it known that I, WIL IAM HAzLnToN, acitizen of the United States of America, residing at Delaware, in thecounty of Delaware and State of Ohio, have invented (certain new anduseful Improvements in DoubleeCement-Block Machines, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

Thisinvention relates to a double cement block machine and has for itsobject the production of a simple and efiicient means for shifting themolds of the cement block from under theftamper so as to facilitate theremoval of the blocks from the mold boxes.

Another object of this invention is the production. of a simple andefficient means for holding the mold boxes in a removable position, andalso facilitating the release of the several parts of the box to permitthe contents of the box to be readily discharged therefrom.

With theseand other objectsin view this invention consists of certainnovel combinations, constructions, and arrangements of parts as will behereinafter fully described and claimed.

In the accompanying drawings a-Figure 1 is a side elevation of thecement block machine. Fig. 2 is a section taken on line 2-2, of Fig.1.Fig. 3 is a top plan view of the cement block machine. Fig. 4 is acentral longitudinal section through the machine. Fig. 5, is a sideelevation of the block molds taken upon the opposite side from thatshown in Fig. 1. Fig. 6 is a section taken on line 6-6, of Fig. 1. Fig.7 is a section taken on line 7-7, of Fig. 1. Fig. 8 is a detailperspective of one of the mold boxes. Fig. 9 is a detail perspective ofone end of the frame of thedevice. Fig. 10 is a detail perspective ofthe bracket which is adapted to carry the connecting pulley for thecement 1 boxes or molds. Fig. ll is a section taken on line X.-X, OfFig. 3. Fig. 12 is a detail perspective of one of the latch bars. Fig.13 1s an end view of one of the latch bars showing the manner in whichthe latch bar engages one of the locking arms, the locking arm beingshown in section. Fig. 14 is a vertical section through the togglemachine for actuating the latch bars. Fig. 15 is. a detail perspectiveof the stop bracket used 1n connection with the present invention.

By referring to the drawings it will be seen that 1 designates the framewhich is supported-upon a plurality of legs or standards ;2 placed ateach end thereof, and an auxiliary frame 3 is. carried intermediate theframe 1 and comprises av plurality of standards or legs 4. The frame 1.comprises a plurality of longitudinally extendingrails having a track 5which has an upper convex face upon which fits the concave track 6,which track is carried by the respective mold boxes 7 hereinafterdescribed. The auxiliary frame 3 carries a drum 7 and this drum issupported upon a shaft 8, and to this shaft 8 is. secured a crank wheel9 for facilitating the rotation of this drum 7. A pulley sheave 10 issecured ateach end of the frame 1. as clearly illustrated inFig. 1 ofthe drawings, and a pulley 11 is mounted within each sheave over whichpulley are adaptedto pass the cables 12. It should be understood thattwo of these cables are employed one cable extending opposite to theother as illustrated in Fig.4 and being secured to opposite sides ofthedrum 7 as illustrated clearly invFig. 4 of the drawings. The cables 12extend around the respective pulleys 11 as above described and alsoextend, aroundthe pulleys 13,,carried by the pulley sheaves 14: securedto the bottom of the mold boxes 7. The opposite ends of the cables 11are then fixedly secured to the respective ends of the frame 1 asindicated clearly in Figs. 3 and t of the drawings.

As stated above a pair of'these mold boxes 7 are employed, andtheseboxes are held in spaced relation by means of a spacing or coupling band15 which is detachably secured to therespective boxes 7 bymeans of boltsldillustrated in Fig. 4. It will, therefore,'be seen that it is onlynecessary to have the pulley sheaves connected to oneend of the boxes 7although, of course, it should be understood that these sheaves may beplaced at each end of the box where only one box is desired, as the samemay be used with one box in place of two boxes as will be clearlyunderstood and without departing from the spirit of the invention.

It, of course, should be understood that the boxes 7 are adapted to beplaced under a tamper forthe purpose of packing the cement, within themold, and when it is desired to remove the boxes, the tamper is releasedand the boxes moved toward theoppo site end of the frame to that shownin Fig. 1. Each box 7 is provided with a hinged front plate 17 clearlyillustrated in detail in Fig. 8, and this hinged front plate 17 issecurely hinged to the base of the box 7 by means of a pintle 18. Thebox 7. is also provided with a pair of hinged end partitions 19 whichare securely hinged to the box 7 by means of pintles 20. These endpartitions 19 are provided with a plurality of spaced arms .21, whichspaced arms project beyond the ends of the respective end partitions 19.

As clearly illustrated in Figs. 1 and 8 of the drawings itwill be seenthat the front plate 17 carries a pair of parallel longitudinallyextending latch bars 2 1, which latch bars are provided with a pluralityof spaced notches formed in their respective ends thereof for thepurposeof fitting against or over the inner edges of the arms 21. Theselatch bars 24:.are connected together by meansof the toggle members 26,one of the toggle membersbeing provided with a stop, lug 27 of the usualconstruction for limiting the toggle members 26in one direction. An.operating handle28 is pivotally secured to the front plate 17 and isconnected to the pivot pin 29 of the toggle members 26 by means of alink 30. It will, therefore, be seen that when it is desired to draw thelatch bars 24 out of engagement 'of a bolt 36. This stop bracket 35 iswith the inner faces of the arms 21, the lever 28 is swung inv onedirection for releasing the latch bars, but when the latch bars aredesired to be locked into engagement with the arms21 it should beunderstood that the operating lever or handle 28 is swung in theopposite direction. By carefully considering Fig. 8 it will be seen thatthe upper arm 21 of each end partition is provided with a projectinghand-hold 31 for facilitating the handling of the box and also thesetting of the same in the desired position.

. It should be. further understood that the latch bars 24 by having aplurality of notches 25 at each end thereof will permit the endpartitions 19 to be adjusted to the position shown in dotted lines inFig. 3 to permit the formation of a block having ends tapering towardone side thereof such as for instance for the purpose of forming a silobloek, which construction is, of course, necessary in order to produce acircular formation of a silo. It should be understood that therearplates 32 of the boxes 7 are reinframe 1. It should be understoodthat one of these brackets 35 is positioned at each end of the frame 1.

A door supporting bracket 38 is support- 7 ed near one end of the frame1 upon one of the legs 2 and also upon one of the legs 4: of

the auxiliary frame 3, these brackets being so placed as to be direct infront of the boxes 7 when the same are moved toward one end of theframe 1. Each bracket 38 is provided with an upwardly extending lip 39for limiting the forward movement of the front panel 17 as the same ismoved downwardly or thrown downwardly to this position. This lip ortongue 39 will prevent the forward movement of the box 7 as the cementblock which has been formed therein is being removed therefrom. Asstated above and as clearly illustrated in Fig. 1, these brackets 38 arepositioned correctly so as to receive the front panels 17 as the sameare swung downwardly for the purpose of releasing a cement blocktherefrom.

Having thus described the invention what is claimed as new, is

1. In a machine of the class described, the combination of a frame,tracks fixedly mounted upon said frame, said tracks having convex upperfaces, mold boxes positioned upon said frame, longitudinally ex- 9tending tracks fixedly mounted upon the lower portions of said boxes,said last-mentioned tracks having concaved lower faces, saidlast-mentioned tracks fitting throughout their entire length upon saidfirst mentioned tracks, whereby said boxes will be supported throughouttheir entire length and thus be positively prevented from sagging, andmeans for drawing said boxes across said frame.
